PicoCam: High‐resolution 3D imaging of live animals and preserved specimens

Methods in Ecology and Evolution, Volume 15, Issue 11, Page 1980-1989, November 2024.
Abstract The PicoCam system is a multi‐camera photogrammetry rig used for generating high‐resolution 3D models of animals in the field, or preserved specimens in laboratory or museum settings. The digital measurement of 3D models is increasingly useful for studying body shape. However, methods that capture sub‐millimetric detail often do so at the cost

The fireball of November 24, 1970, as the most probable source of the Ischgl meteorite

Meteoritics &Planetary Science, Volume 59, Issue 7, Page 1658-1691, July 2024.
Abstract The discovery of the Ischgl meteorite unfolded in a captivating manner. In June 1976, a pristine meteorite stone weighing approximately 1 kg, fully covered with a fresh black fusion crust, was collected on a mountain road in the high‐altitude Alpine environment.

Remote sensing of Antarctic polychaete reefs (Serpula narconensis): reproducible workflows for quantifying benthic structural complexity with action cameras, remotely operated vehicles and structure‐from‐motion photogrammetry

Remote Sensing in Ecology and Conservation, Volume 10, Issue 1, Page 72-90, February 2024.
Quantifying the structural complexity provided by biogenic habitat structures, particularly in deep sea and polar environments, is important in ecology, conservation and management, but yet remains a challenging task that current photogrammetry tools can alleviate.

Active Shortening Simultaneous to Normal Faulting Based on GNSS, Geophysical, and Geological Data: The Seismogenic Ventas de Zafarraya Fault (Betic Cordillera, Southern Spain)

Tectonics, Volume 43, Issue 2, February 2024.
Abstract The central Betic Cordillera, southern Spain, is affected by an uplift related to the NNW–SSE Eurasia‐Nubia convergence and shallow ENE–WSW orthogonal extension accommodated by the extensional system of the Granada Basin. The combination of geophysical, geodetic, and geological data reveals that the southwestern boundary of this extensional ...

Closing the gap between existing large‐area imaging research and marine conservation needs

Conservation Biology, Volume 38, Issue 1, February 2024.
Abstract Emerging technology has immense potential to increase the scale and efficiency of marine conservation. One such technology is large‐area imaging (LAI), which relies on structure‐from‐motion photogrammetry to create composite products, including 3‐dimensional (3‐D) environmental models, that are larger in spatial extent than the individual ...
